2016 ANNUAL REPORT INTRODUCTION The Armed Forces Radio biology Research Institute (AFRRI) reactor facility was available for irradiation services for the entire year until December 7 when it was shutdown to prepare for the installation of a new instrumentation and control system by contractors from General Atomics, scheduled to begin in January 2017. The reactor license renewal application, submitted in June 2004, was approved by the NRC with the issuance of a new 20-year operating license on November 30, 2016. Numerous revisions to both the Technical Specifications and the Safety Analysis Report were submitted as part of the relicensing process and were approved by the NRC.

There were no major reactor modifications or projects during the year except preparation for installation of the new reactor console after December 7. There were no unscheduled shutdowns during 2016.

The 20 l 6 annual reactor audit required by the reactor technical specifications was conducted by Mr. Bob Woodruff in January 2017. Mr. Woodruff is a health physicist in the Military Medical Operations Division. During the audit he verbally indicated that he had not found any major discrepancies in reactor operations and those conclusions are reflected in his written report.

A comprehensive NRC inspection of reactor facility operations and security was conducted by Mr. Johnny Eads during January 2016. While he had several recommendations for improving reactor operations, no safety concerns or noncompliance with NRC requirements were identified.

There were two RRFSS membership changes during the year. There were two reactor staff arrivals and three staff departures during the year.

The remainder of this report is written in the format designated in the Technical Specifications for the AFRRI TRIGA Reactor Facility. Items not specifically required are presented in the General Information section. The following sections correspond to the required items listed in Section 6.6.b. of the Technical Specifications.

There were no reactor malfunctions during 2016.

I L__ _

The 2016 annual reactor audit required by the reactor technical specifications was conducted by Mr. Bob Woodruff in January 2017. Mr. Woodruff is a health physicist in the Military Medical Operations Division. During the audit he verbally indicated that he had not found any major discrepancies in reactor operations and those conclusions are reflected in his written report.

A comprehensive NRC inspection of reactor facility operations and security was conducted by Mr. Johnny Eads during January 2016. While he had several recommendations for improving reactor operations, no safety concerns or noncompliance with NRC requirements were identified.

• Fuel-followed control rods

SECTION III Unscheduled Shutdowns There were no unscheduled shutdowns during 2016.

SECTION IV Safety-Related Corrective Maintenance There were no reactor malfunctions during 2016.

SECTIONV Facility and Procedure Changes as Described in the Final Safety Analysis Report (FSAR), New Experiments or Tests Performed During the Year A. FACILITY CHANGES AS DESCRIBED IN THE FSAR Chapter 7, Instrumentation and Control Systems and Chapter 13, Accident Analysis of the FSAR were extensively revised during the reactor relicensing process and were approved by the NRC when the licensed was renewed on November 30.

B. PROCEDURE

CHANGES AS DESCRIBED IN THE FSAR There were no changes to procedures as described in the FSAR.

C. NEW EXPERIMENTS OR TESTS No new experiments or tests were performed during the reporting period that were not encompassed by the FSAR.

There were two safety evaluations for changes n.ot submitted to the NRC, pursuant to the provisions of 10 CFR 50.59 (see Section l.D. above).

SECTION VI Summary of Radioactive Effluent Released A. Liquid Waste: The reactor produced no liquid waste during 2016.

B. Gaseous Waste: There were no particulate discharges in 2016.

The total activity of Argon-41 discharged in 2016 was 1.07 curies. The estimated effluent concentration from the release of Argon-41 represents under 1% of the constraint limit for unrestricted areas (10 CPR 20.l lOl(d) and Table 2, Appendix B, 10 CPR 20).

Quarterly: Jan - Mar 2016 0.70 Ci Apr - Jun 2016 0.01 Ci Jul - Sep 2016 0.36 Ci Oct - Dec 2016 0.00 Ci C. Solid Waste: All solid radioactive waste material was transferred to the APRRI byproduct license; none was disposed of under the R-84 reactor license.

SECTION VII Environmental Radiological Surveys All environmental sampling of soil and vegetation yielded radionuclide levels within the background range. The radionuclides that were detected were those expected from natural background and from long-term fallout from nuclear weapons testing.

The calculated annual dose, due to Argon-41 release to the environment for 2016, was 0.06 mRem at the location of maximum public exposure. The maximum exposure is calculated at a location 91 meters from the release point as described in the PSAR. Exposure to the general population at the boundary of the Naval Support Activity Bethesda is significantly less due to the diffusion of Argon-41 in the atmosphere. The constraint limit for exposure to the public

• established under 10 CPR 20.l lOl(d) is 10 millirem per year. The exposure dose was calculated using COMPLY code, level 2, which is the most conservative level of COMPLY. Emissions due to reactor operations were 0.06 millirem, or less than 1% of the 10 millirem constraint limit, for the entire year.

The reactor in-plant surveys, specified in Health Physics Procedure (HPP) 3-2, all resulted in readings that were less than the action levels specified in HPP 0-2.

SECTION VIII Exposures Greater than 25% of 10 CFR 20 Limits There were no doses to reactor staff personnel or reactor visitors greater than 25% of 10 CFR 20 occupational and public radiation dose limits.
